Asthma Identified as Risk Factor for Postoperative Complications After Gastrectomy for Gastric Cancer

A team of researchers from Ishikawa Prefectural Central Hospital in Japan has conducted a retrospective analysis of 1,001 patients who underwent gastrectomy for gastric cancer to investigate the relationship between asthma and postoperative complications. The study found that asthma was a significant risk factor for postoperative pulmonary complications and intra-abdominal infectious complications. The researchers analyzed clinical data from April 2010 to December 2022 and identified risk factors for postoperative complications using univariate and multivariate analyses.

Key Takeaways:

• Asthma was identified as a risk factor for postoperative pulmonary complications and intra-abdominal infectious complications after gastrectomy for gastric cancer.
• The study analyzed 1,001 patients who underwent gastrectomy for gastric cancer from April 2010 to December 2022 at Ishikawa Prefectural Central Hospital.
• Risk factors for postoperative complications were identified through univariate and multivariate analyses, which included asthma, hypertension, male sex, and higher body mass index.
• The hazard ratio for the presence of asthma had the highest value at 3.08 (95% confidence interval 1.610-5.870, p Not specified in the source).
• The frequency and types of complications were evaluated in patients with and without asthma.
• The study concluded that asthma is a risk factor for postoperative complications and should be taken into account by surgeons and anesthesiologists when planning surgery.

Statistics:

• 1,001 patients were included in the study, which spanned from April 2010 to December 2022.
• 3.08 was the hazard ratio for the presence of asthma, indicating a significant risk factor for postoperative complications.
• 95% confidence interval of 1.610-5.870 was obtained through the study's multivariate analysis for asthma.
• 34.56% of complications were related to gastrointestinal disorders, according to the source.
